Our Pan Head Machine Screws are one of the most versatile and widely used fasteners for general assembly and manufacturing. Characterized by their slightly domed head with a flat bearing surface, these screws provide a clean finish and reliable clamping force. As a factory-direct product, we offer these screws at a competitive price with extensive customization options, including a vast range of materials, grades, finishes, and compliance with multiple international standards (ISO, DIN, ANSI, JIS, etc.). They are the go-to choice for countless applications in machinery, electronics, and general fabrication.

Product Details

The “pan head” is a classic screw head style, often referred to as a “round head,” that combines a low-profile, slightly rounded top with a flat underside. This design provides a large, flat bearing surface that distributes the clamping load evenly, making it an excellent choice for securing thin materials without damage. The raised head also makes it easy to install and remove.

As a “machine screw,” it features a straight shank with fine, uniform threads designed to be fastened into a pre-tapped hole or used in conjunction with a nut. This ensures a precise, strong, and repeatable connection. We can manufacture these screws with various drive types, most commonly Phillips or Slotted, to suit different assembly requirements.
